    Abstract: The invention provides a method for separating one or more triorganophosphite components from a crude phosphite mixture containing acidic hydrolysis products, the method comprising: contacting said crude phosphite mixture with a basic additive to produce a second mixture comprising a first phase and a second phase, wherein said first phase comprises the basic additive and one or more components independently selected from the group consisting of (R2O)(R3O)POH, (R1O)(HO)PO(H) and H3PO3, wherein R1, R2 and R3 are independently selected from the group consisting of C1 to C18 alkyl, C6 to C18 aryl and hydroxyaryl, and C3 to C18 cycloalkyl and hydroxyalkyl radicals, and wherein R2 and R3 can optionally be connected to each other directly by a chemical bond or through an intermediate divalent group R9; and said second phase comprises one or more triorganophosphite components independently selected from the group consisting of (R4O)(R5O)P(OR6) and ((R7O)(R8O)PO)nA, wherein R4, R5, R6, R7 and R8 are independently selected from the group consisting of C1 to C18 alkyl, C6 to C18 aryl and C3 to C18 cycloalkyl radicals, wherein each of R4, R5 and R6 can optionally be connected to one or both of the other two directly by a chemical bond or through an intermediate divalent group R10, wherein R7 and R8 can optionally be connected to each other directly by a chemical bond or through an intermediate divalent group R11, wherein A is an optionally substituted or unsubstituted aliphatic, aromatic or heteroaromatic radical, and wherein n is an integer greater than 1; and R9, R10, and R11 are independently selected from the group consisting of - O-, -S-, and -CH(R12)-, wherein R12 is selected from the group consisting of H, C6 to C18 aryl, and C1 to C18 alkyl.

    Abstract: Provided by this invention is a modified synthetic polyamide polymer yarn produced by an improved melt extrusion process. Yarn of this invention are either partially oriented yarns (POY) or drawn oriented yarns. The improved process provides for modification of a polymer in a melt extruder. Following this modification of the polymer, a filament forming process step is provided which is coupled to a drawing stage prior to winding a package of yarn.

    Abstract translation: 公开了一种纺丝聚酰胺长丝并提供纱线的方法，包括以下步骤：将聚酰胺聚合物提供给熔体挤出机; 提供能够支化聚酰胺聚合物的三氨基化合物; 将所述三氨基化合物加入到所述熔体挤出机中的注入点，所述注入点选择为所述三氨基化合物和所述聚酰胺聚合物提供足够的接触时间以形成熔融聚合物;熔化所述聚酰胺聚合物; 和挤出熔融聚合物以形成支化聚酰胺聚合物长丝。 由改性尼龙66聚合物形成的聚酰胺纱线具有40至55的甲酸相对粘度（RV），60％至100％的断裂伸长率，三聚氨基化合物含量为0.01至0.10重量％，由 该方法还包括小于约2.0的拉伸比。
